Everything you need to know about repairing your videos with VideoRepair.
Select your corrupted video file. Optionally add a reference file from the same device for better results.
Our AI-powered engine automatically analyzes the file structure and repairs the damaged metadata — all locally in your browser.
Preview the repaired video and download it to your device. Your file is ready to play.
VideoRepair currently supports MP4, MOV, M4V, M4A, and 3GP formats with H.264 video and AAC audio codecs. We are actively working on adding support for more formats including MKV, WebM, and AVI.
The maximum supported file size is 500 MB. Files are processed in chunks using streaming architecture, so even large files can be repaired with minimal memory usage.
All video processing happens entirely in your browser using WebAssembly technology. Your files are never uploaded to any server. The repair engine analyzes the file structure, identifies corruption, and rebuilds the damaged metadata to restore playability.
Absolutely. Privacy is our top priority. All video processing is performed locally in your browser — your files never leave your device. We do not collect, store, or transmit any of your video data.
A reference file is a normal, playable video recorded by the same device and settings as the corrupted file. It helps the repair engine obtain the correct codec parameters (such as resolution, frame rate, and encoding profile) when the corrupted file is missing this information entirely. Using a reference file significantly improves repair success rates for severely damaged videos.
You can repair and preview videos without an account. However, a subscription is required to download repaired files and use the batch repair feature. Creating an account also enables you to keep a full repair history.
You can cancel your subscription at any time through the Pricing page. Click the "Manage Subscription" button to open the subscription portal, where you can cancel, change plans, or update your payment method. Your access will continue until the end of the current billing period.
